As we reported, Kristin Cavallari's brother — Michael Cavallari — was last seen 12 days ago at a gas station in Utah. His vehicle was later found abandoned, with its engine running and its air bag deployed.

While authorities are still trying to figure out his whereabouts, information from his past has surfaced that shows he was a troubled character with several ailments.

According to Daily Mail, the 30-year-old suffered from alcohol abuse which only amplified his psychological issues.

Before he went missing, Cavallari lived in his father Dennis' $6.6 million house in San Clemente, CA where he spent his days smoking cigarettes, drinking booze, and playing online poker, instead of finding a job.

His father's property had several rented out guest houses, whose residents would often complain about Michael's commotion.

In fact, one neighbor recounts MC would walk around the backyard screaming, "the CIA is coming to get me."

In the video — where the college student makes amends with the cafeteria food staff and manager, as well as his own family and friends who he feels he has disappointed — Gatti mentions in passing about addressing his problems and getting help that he needs.

He doesn't go into what that is, but whatever the case may be, here's to him coming out of this a much better person than he had been before.

Blake was reportedly in Cancun recently for a friend's bachelor party and witnesses say he hit the tequila HARD while he was out! One source says:

"He was doing shots of tequila nonstop and partied with strippers all weekend… Things got more and more wild each day he was there."

Blake reportedly brought two ladies back to his hotel room with a couple bottles of tequila, and the three spent some time in the hot tub before eventually moving to the bedroom!

And apparently he was NOT holding back on the PDA!

Friends were quick to point out that Blake has always loved to party, but it sounds like he's taking it to a whole new level now!

In fact, some friends are even urging him to take some time off and enter a rehab program! However, sources say Blake believes returning toThe Voicemight end up being the best medicine for his broken heart!

We definitely hope Blake gets the help and support he needs, because going through a breakup is NEVER easy!

The reality TV star has two children — Lorenzo, 2, and Giovanna, 8 months — who don't always give mommy an easy time!

The fistpumper candidly confesses that her son in particular is quite the troublemaker!

She said:

"Lorenzo's a pain in the ass… I mean I love him to death, but he's a pain in the ass, he's going through his terrible twos. He talks back to me, he doesn't listen, but the good thing is he's terrified of timeout…so if he ever acts up, I'm like ‘you're going in timeout' and then he stops."'
